Lightening bolt mani fail

Hi everyone

I looooooove Nailside, she makes the most fabulous manicures... So of course I wanted to try the double lightening bolt mani and of course I read the tutorial and of course I forget how it exactly done and of course I was too lazy to start my computer and check

And of course it results in a fail :p
I'm really want to try this again, and do it correctly...
